MAT FOR COMPRESSION-BOXES.

Application filed September 10, 1915.

To all whom t may concerne:

Beit knownthat I, MICHAEL B. GREEN, a citizen of the United States, residing at Memphis, inthe county of Shelby and State of Tennessee, have invented new and useful Improvements in Mats .for Compression- Boxes', of which the following is a `specification.

This `invention .relates to oil presses `and more particularly to the-mats to be used in connection with the compression boxes of cotton-seed and ylinseed presses.

The present invention is designed as 4an improvement upon former mat plates and also to produce a device whereby the maximum quantityof oil may be obtained from the cake in a minimum lengthof time. It is believed that with the present invention the advantage of quantity attained in the use of the old yhair `mat with the speed of the perforated plate `is attained in the present invention without the attending disadvantages in the hair Amat and perforated plate, the hairmat process being extremely slow andthe common perforated plate being undesirable on account of its distortion under pressure.

Another-object ofthe invention is the provision of means whereby thenumber or holes in the mat plate may be increased to a great degree without weakening the plate to such an extent that it will warp or become distorted under pressure and which improves upon the inherent good qualities ofthe old hair mat and perforated plate.

Furtherobjects ofthis invention will appear as the following `specific description is read in connection with the accompanying drawings which form a part of this application, andk in which Figure 1 is a side elevation of an oil press showing a number of the boxes in section. Fig. 2 is a top plan view of one` of the boxes with the parts broken away. yFigi-3 is a detail'longitudinal section looking sidewise at one `of the bars. Fig. 4 isa detail Atransverse sectional view taken on the line 1 -4 of Fig. 2. Fig. 5 is a perspective view of one of the bars. Fig. 6 is a detail perspective view of one corner of the plate on a somewhat enlarged scale.

The oil press consisting of the base 1, uprights 2, head 3 and ram plunger 4 need not be specifically described herein, being well understood by those versed in the art. The press, of course, carries a plulllty O bOXeS Specification 0f Letters Patent.

as is usual, indicated at 5. Mounted upon the base of each box and arranged to iit within the guide strips or upper half of the box, are a plurality of bars 7 connected together by transverse rivets 8, or in any other suitable manner so as to produce a unitary structure. The bars, with the exception of the outside bars, are constructed alike, therefore, the description of one will suffice for all. These bars are substantially rectangular in cross-section and have in each side adjacent the top thereof, a semi-circular groove or channel 9 which, when the bars are riveted together as shown in Fig. 4, act to form circular channels 10 of enlarged diameter'so as to provide for a free flow of oil as will be hereinafter described. The upper part of the bars above the channels or grooves are formed with slots 11, for purposes of illustration we will say approximately one-eighth of an inch in width. These slots extend from the center outwardly and downwardly on an inclined line so as to lcommunicate with the grooves 9 and are staggered as shown in the drawings, i. c. one slot extending to one side of the bar and communicating with the groove 6 on the right-hand side while the next adjacent but separated slot extends from the center to the left and communicates with the groove on the left-hand sideof the bar, each having, of course, the inclined inner wall as indicated at 12. Then assembled the slots of the adjoining bars are in register so as to form one substantially V-shaped slot leading into the enlarged channel 10 formed by the grooves ofthe adjoining bars.

The bars are flat upon their upper surfaces and resting thereon and secured thereto by four screws or lag bolts 13, one at each corner, is a mat plate 14:. This plate has a longitudinal series of transversely extending corrugations 15 in the valleys of which are located separated series of apertures or ports 1G each series being positioned above one of the V-shaped slots andy being staggered in one row with the series of slots in the adjacent row. Byproviding the corrugations as shown, and staggering the series of openings in the plates, I am not only enabled to increase the number of holes over the ordinary perforated plate by about ive to one but I also increase the strength of the plate materially and thereby eliminate distortion under pressure to a considerable extent. The hples are preferably all tapered as shown from their upper to their lower ends and each series is preferably connected upon its under side with a slotv 17 of equal width and length with the registering slots l in the upper face of the bars.

lVhen the cakes are interposed between the' mat and the upper portion of the box and the ram operated in the usual manner to apply pressure oil will pass through the holes 16 and into the slots l1 from thence passing into the channels l0 onto the base of the box, being drained from the upper boxes to the lower boxes and into a suitable receptacle as is customary. The tapering of the holes from their upper ends to their lower ends prevents particles of the cake from wedging into the holes and permits a free iiow of oil at all times. rIhe number of holes being increased, the capacity of the press is greater and, therefore, its speed increased and it has been found in practice that with a structure of this type, approximately the same amount of oil is obtained from a given quantity of meal as is obtained with the same quantity in using the hair mat.

What is claimed is 1. A mat for oil presses comprising a plurality of bars having lateral grooves forming oil discharge channels between the meeting faces thereof, said bars being provided with transverse slots in their opposite edges communicating with said grooves, and the slots of adjacent bars being in registry with each other to form V-shaped pockets communicating with the discharge channels.

2. A mat for oil presses comprising a plurality of bars provided in their lateral faces with longitudinal grooves coperatively forming oil discharge channels, the portions of the bars disposed above and overhanging the grooves being provided with lateral slots communicating with the channels, the slots in the opposite edges of the bars being staggered with relation to each other, and the slots of contiguous sides of adjacent bars registering to form V-shaped pockets communicating with the intervening channel.

3. A mat for oil presses comprising a plurality of bars provided with grooves in their meeting faces collectively forming discharge channels, the side portions of the bars above the grooves being transversely slotted to provide drain passages, the walls of the slots of adjacent bars inclining downwardly and inwardly toward the intervening discharge channel, the slots in the opposite edges of each bar being arranged in staggered relation and the :slots in contiguous sides of adjacent bars being in registering relation to provide V-shaped pockets communicating with the intervening channels, and a plate resting upon said bars and provided with groups of openings communicating with the respective pockets.

4. A mat for compressing boxes comprising a plurality of longitudinal bars having grooves in their sides, means for joining the bars together, whereby the grooves produce oil receiving channels, staggered slots in each side of the bars extending from the upper surface to the groove and having inclined inner walls, said slots being staggered on opposite sides of the bars, the slots on one side of one bar arranged to register with the slots of the adjacent side of the next adjoining bar and to lead directly to a channel, a plate mounted upon the bars and having apertures communicating with the slots and means for securing the plate to the bars.

5. A mat for compressing boxes comprising a plurality of longitudinal bars having grooves in their sides, means for joining the bars together, whereby the grooves produce oil receiving channels, staggered slots in each side of the bars extending from the upper surface to the groove and having inclined inner walls, said slots being staggered on opposite sides of the bars, the slots on one side of one bar arranged to register with the slots of the adjacent side of the next adjoining bar and to lead directly to a channel, a plate mounted upon the bars and having apertures communicating with the slots, said apertures being arranged in staggered rows and being tapered with their largest diameter adjacent the slots and said plate beingY corrugated with apertures in the trough of the corrugations.

ln testimony whereof l affix my signature in presence of two witnesses.
